Oristhorchiasis is a helminthic disease caused by the cat (Siberian) fluke (opisthorchiasis), a flatworm 4-13 mm long. Adult opisthorchises parasitize in the bile ducts of the liver, gall bladder and pancreatic ducts in humans, cats, dogs, and fur-bearing animals. From here, the eggs laid by the parasites enter the intestines and are thrown out with feces.

Eggs that fall into freshwater bodies are swallowed by mollusks, in which tailed larvae (cercariae) develop from the eggs. Cercariae emerge from the mollusk into the water, penetrate the body of carp fish (ide, dace, chebak, etc.) and settle under their skin and in their muscles. Infection of humans, cats, and dogs occurs by eating raw (frozen, lightly salted) and insufficiently cooked (fried) fish.

To prevent infection with opisthorchiasis, it is necessary to eat fish only after boiling (at least 20 minutes), well-frying in fat for 20-30 minutes. The ambassador neutralizes the fish only after 10-25 days. When frozen, opisthorchis larvae remain alive for up to 2-4 weeks. To prevent opisthorchiasis, it is important to protect water bodies from pollution by sewage.
